INCANDESCENT IGNITER FOR EXPLOS-lVE-MOTORS.

SPECIFICATION forming part of Letters Patent No. 682,933, dated September 1'7, 1901.

Original application filed May 4, 1899, Serial No. 715,671. Divided and this application filed May 23, 1900. Serial To all whom it may concern:

Be it known that LRAsMUs PEDER HAN- sEN, a subject of the King of Denmark, and a resident of Erindslev Sogn Rodby, Denmark, have invented certain new and useful Improvements in Incandescent Igniters for Explosive-Motors, of which the following is a specification.

My invention relates to an igniting-tube for automaticallyigniting the explosive mixture in explosion-motors. V

The ignitingtube is represented in the accompanying drawing, which shows a vertical section through the upper part of a motorcylinder with the igniting -tube arranged therein.

A is the motor cylinder, which is closed at its upper part by a hollow lid or cover B, the hollow space 0 of which is in open connection with the hollow space of the cylinder.

The igniting-tube D is made of copper and is closed at its upper extremity. The igniting-tube, whichis thin-walled, has at its open (No model.)

or in the hollow space 0 will quickly rise so high that the igniting-tube becomes very hot. While the compression rises, the degree of heat rises more, and when the compression has reached the highest degree the heat will be so high that the igniting-tube becomes incandescent and ignites the explosive mixture.

What I claim, and desire to secure by Letters Patent, is-

1. In explosion-motors, an extension of the explosion-chamber formed in the cover and communicating therewith, an igniting-tube projecting into said extension of the explosion-chamber the closed extremity of the igniting-tube being provided with thin walls; substantially as described.

2. In combination with an explosive-engine cylinder, a cover closing the end thereof and having a chamber therein communicating with the cylinder, said cover having an opening through its wall to one side of the said communication with the cylinder, and a hollow ignition-tube seated in said opening and having its walls projecting into said chamber, the interior of said ignition-tube columnnicating with the cylinder, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
